Hi @queen1978, welcome to Connect.
I moved your message about MALT lymphoma to the Blood Cancers & Disorders group so that you can meet others living with lymphoma. While we wait for others to join the discussion, you might be interested in following the Hematology page on Connect (https://connect.mayoclinic.org/page/hematology/) and reading the blogs.
I truly understand your concern about radiation given the stories that you have about people close to you. Radiation has come a long way in 40 years and dosages are much more precise. Head and neck cancers are very different from lymphoma.
